Figure 16: Inserting an OnStream ADR cartridge

wind the tape to the main directory.
Caution!
ADR 50 GB cartridges are longer than ADR 30 GB cartridges,
preventing the cartridge door from closing completely. Do not attempt to pull
an ADR 50 GB cartridge out of the drive!
Removing a Cartridge from the Drive
1.
Press the eject button on the left side of your OnStream SC30/SC50 Digital
Tape Drive’s front panel as shown in Figure 16. The cartridge door opens and

It may take a few seconds to eject an OnStream ADR cartridge. Your OnStream

directory before ejecting the cartridge.
2.
Remove the cartridge immediately.
After a few seconds the cartridge door closes automatically. Do not press on the
door while it is open.

incremental backups to the corresponding tape. At the end of the week, make
